ColdFusion 8 - Application.cfc干扰

问题描述 投票：1回答：2

我刚刚与客户的网站有一个奇怪的问题，我的实时域名正在使用我的开发域应用程序设置。我之前没有遇到过这个问题，并且在cflock（以及其他设置）中移除Application.dsn解决了这个问题。

如上所述我有一个实时网站*www.*和开发网站*dev.*，我的开发网站是在现场网站/dev/的子文件夹中，并拥有它自己的Application.cfc。

我的第一个问题是，如果我在dev文件夹中的Application范围中有变量，那么这会覆盖上面文件夹中的Application范围变量吗？它会认为它是同一个范围吗？如果是这样，那么这可能解释了什么问题，如果没有，那么我很难过。

我的第二个问题是，如何在application.cfc中更正cflock应用程序范围变量？我应该这样做吗？

这是我的Application.cfc，建议将不胜感激：

为什么要根据其所处的环境更改应用程序名称？这是没有意义的。该应用程序仍然是相同的应用程序，无论它是在prod，或你正在进行，或开发它。

同样，与源代码相同。您的实时网站中有自己的开发网站？这有什么用呢？

我不知道你的应用程序变量是怎么回事，但它们与应用程序名称（this.name）绑定，而不是Application.cfc在目录结构中的位置。

我怀疑你的零applicationTimeout在这里没有多大帮助。这基本上意味着您的应用程序永远不会持续存在......它将超时每个请求。这没有任何意义。

你不需要在<cflock>中使用onApplicationStart()代码。 ColdFusion只允许一个请求运行onApplicationStart()：所有其他请求将排队，直到它完成，此时应用程序已启动，因此排队的请求甚至不会尝试运行它。

我认为你的问题很可能是由你糟糕的应用程序框架设计引起的，而这个奇怪的事情是你在同一个源代码树中使用dev和prod（它违背了所有逻辑）。

对源代码进行排序，不会出现问题。

您可以使用条件逻辑来设置应用程序名称。

if ( YouAreHappy and YouKnowIt ) {
This.name = "ClapYourHands";
}
else {
This.name = "StompYourFeet"; 
}

在现实生活中，你的if条件会使实时和测试环境不同。 cgi.http_host是一个很好的候选人。
